The issue of prescribed performance platoon control of connected vehicles with dynamic performance threshold is investigated in this paper. A continuous gain function is intro-duced, combining with finite-time performance function, a novel prescribed performance control (PPC) scheme is developed to make the tracking error tend to the prescribed region with different threshold within the user-defined time. Then, a new finite-time reaching law is proposed, based on which, an improved finite-time sliding mode platoon control algorithm is proposed. The suggested control strategy not only ensures finite-time individual vehicle stability and finite-time string stability, but also realizes the asymptotic convergence of the spacing tracking error. Eventually, the feasibility of the proposed scheme are validated by numerical simulations.
